The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
A second class lever always has a mechanical advantage greater than 1.
mechanical advantage is the output force divided by the input force
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
always less than 1
second class lever

always less than 1
... is always less than 1 .
idk go ask your teacher
because they are smaller than the level 3 that's why
Multiply (the input force) x (the lever's mechanical advantage).
Second class lever. . . . Always greater than 1 . Third class lever . . . . . Always less than 1 . First class lever . . . . . Can be greater than 1 or less than 1 depending on position of fulcrum.
